Embodiment Construction

[0076] Attached below figure 2 The open-pit mine in further illustrates the present invention.

[0077] Unless otherwise marked, the coordinate unit is m. Part of the data given in the implementation is rounded to two decimal places, and there is no rounding in the actual calculation process.

[0078] Step 1. Select the midline of a certain level of transportation road on the side wall as the reference polyline, and the range of the side wall selected must intersect with the range of the stope and the inner dump. Choose to attach figure 1 A in 1 B 1 C 1 As a datum polyline with an elevation of Z 0 =840m, the coordinates of each point are A 1 (26877.19,10625.97,840), B 1 (29091.25, 11645.12, 840), C 1 (31070.50,11703.37,840), for point coordinates Indicates (A 1 , B 1 、C 1 Corresponding to i=1,2,3 respectively)

[0079] Further calculations give the unit direction vectors of each segment of the polyline as Among them, the unit direction vector of the line ...

Abstract

The invention discloses a method for calculating the transportation distance of an open pit coal mine inner row. The transportation path and distance of a stripped object can be calculated according to a transportation starting point and a transportation ending point. According to the method, the inner discharging transportation process of the strip mine is simplified; the open pit coal mine end slope geometric characteristics are simplified; an end slope reference multi-segment line is used to perform the geometric mathematical representation on parameters such as slope angles, an end slope offset multi-section line at the elevation of a transportation starting point/ending point is calculated according to the input data of the transportation starting point and the transportation ending point, and a horizontal transportation path and distance and a vertical transportation climbing/downhill distance are obtained by the further calculation.

Description

technical field [0001] The invention belongs to the technical field of open-pit coal mining, and in particular relates to a calculation method for the internal discharge transportation distance of stripped objects. Background technique [0002] The transportation distance of open-pit coal mines is the basic parameter for calculating the transportation cost. It is used for the statistics of internal transportation costs when the transportation is self-operated, and it is used as the basis for the settlement of expenses when the transportation is outsourced. Accurate and reasonable calculation of transportation distance is a key factor in transportation cost calculation and optimization. [0003] At present, in mine production, the method of drawing the transportation path on the drawing and then measuring the transportation distance is mostly used. This method is cumbersome and has a large workload, and the obtained transportation distance is not accurate enough. [0004] I...
